T0 ALLVWHOM IT MAY CONCERN:l i p p v p p Be it known that I, WARREN SHAILER, of Deep River, in the county of Middlesex, in the State of Coni necticut, have invented a new and improved Window Fastener; 'and I do hereby declarethat the following is a H i full'and exact description thereof, reference being had to the accompanyingdrawings, and to the letters lot".

reference marked thereon.

' The nature of my invention consists in constructing window fasteners with one or both sidesiverging i from the top, and having a slot to receive a screw for the, purpose of attaching them tothe sash `and allow the wedge form of the "side to operate between the screw Land casing of the window tohold thelvvindow` inany desired position; vand'also having a recess or hook on. the lower part, on one or both sides, to receive a screw` head or any suitable catch attached -to the casing of the window, an-dfasten thewindow wheniclosedr` To enable others to make and use my invention, I`will proceed to describe its constructiionand operation.` I construct my window fasteners to operate on one or both sides of a window, casting them with any suitable met-al. A, Figure l, represents one constructed to operate on the left-hand side of a window, and its operation in vfastening the window when raised. S represents a slot by which it is attached to thesash by ascrew, on `which i it easily moves up and down. C represents a recess to receive a screw-head or catch, secured to the casing` of a window, and fasten the windowiwhen closed. f

The, mode of attaching, and its operation when attached, are as follows: The divexging` `or wedge; side is placed against the casing and a screw entered a' little above Vthe middle Vof the slot, securingi't to the sash. By

Vplacing the finger or thumb against the bottomof the fastener and lowering the window, it ispheld at any desired height by the wedge-shaped sidel'operatingbetween the casingand the screw.V Raising the window freesitfrom the fastening, the screw slipping up' in the slot, causing the fastener to drop till the top restsupon the screw, in which position it does not interfere with the movement of the window until it is closed." The window is fastened whenlclosed by marking ,theposition ofthe recess C on tle casing and inserting there a screw opposite the` recess, allowing the head to project equal to the depth of the recess. The bottom of the fastener being rounded, p `it is moved'outwardly on coming in contact with the screw in the casing when the window is being lowered, but` i swings back against the casing' when it is closed, the screwfhead entering the recessQ-Whis position is repre.

sented by Figure 2.

i Figure 3 is a detached representation.

Figure 4 represents it constructed to operate on the right or left-hand side of a window. Figure 5 represents-it with the wedge side made wide and the top of the slotcurved towards it, `to adapt it to windows having considerable lateral movement, and also a projection or handle marked e, by which to operate it.`

What I claim as my invention, and desire to secure by Letters Patntfis- The window fastener, substantially as herein described, and represented by figs. 3, 4, and 5.
